The numerical experimental result indicated that perimeter air deflectable deposited burner could ensure the flame stability, prevent spout fire carrying and promote low pollutant emission combustion.

结果表明偏置周界风燃烧器在保证煤粉气流着火稳定性同时，具备较强的防止喷口带火能力及低NOx燃烧能力，并能够保证了水冷壁附近处于相对较高的氧化性氛围，从而解决水冷壁高温腐蚀、结渣等问题。

Then, a series of successful numerical simulations on the finite length inclined positively buoyant jets in uniform cross flows environment are developed. Based on the results from numerical simulations, some qualitative pictures of the complex three -dimensional mean flows are given. In terms of these pictures, the flowing behavior of the buoyant jets and the mechanism of end-vortexes generation are made a study. The change rules of end-vortexes and temperature and dilution on trajectory of jets, horse-hoof shape of buoyant jets on horizontal, the phenomenon of the jets touch wall, and the effects of diffuser length^ densimetric Foroude number % velocity ratio on buoyant jets are also given.

之后对均匀横流环境中的有限长线源型倾斜浮力射流进行了大量的数值计算，根据数值模拟的结果，绘出了一些复杂的三维图，据此探讨了其流动特性及端涡的产生机理，成功模拟了端涡现象及其发展过程，对轨迹线上沿程温度及稀释度的变化规律，倾斜浮力射流的马蹄形结构，浮力射流的贴壁现象，扩散器长度、喷口弗汝德数、流速比等对浮力射流的影响等问题均给出了有价值的结论。

The idea here is to introduce very subtle surface texture changes that represent the slight uneveness brought on by MBT vents, bouys, floodable grating covers and hatches.

这里的想法是引入非常微妙的表面纹理的变化，代表轻微不匀带来的主战坦克是由喷口， bouys ， floodable光栅盖和舱口。

Throughout the morning, Marilla vents inwardly; she can tell from Matthew's countenance that he still wants to keep Anne.

整个上午， Marilla喷口内心，她可以告诉由马修的面容，他仍希望保持安妮。

To solve the practical problem where the temperature field distribution is low at the lower part of furnace chamber and high at the upper part and the temperature difference is untolerable , which is reflected by the thermocouples at site, the authors take the methods of multipoint test and computer hologram simulation to research into the fields in the furnace chamber of the zinc fractionating tower at Shaoguan Smelter CNNC.

针对锌精馏炉炉膛各检测点反映出的其上部温度偏高，下部温度偏低，上下温度偏差过大的实际问题，采用现场多点温度测试，结合炉膛内流场、浓度场、释热场和温度场数值仿真的方法对韶关冶炼厂二精馏系统进行研究；利用仿真结果中的流场扣浓度场数据，统计出实测中无法得到的各次空气和煤气在南1号至南4号各喷口的流量。

Herein, at least one of said separating means (2-5, 6-9) comprises a multiport cyclone into which the material flow to be treated is passed via an infeed nozzle (2, 6) having an annular cross section.

其中至少一个上述分离装置(2～5；6～9)包括多入口旋流器，使待处理的物料流径横截面为环形的进入喷口(2，6)进入该旋流器。

The numerical results are compared with experiment results, it is verified that contribution of the ablated nozzle materials to the over-rise of pressure in pressure chamber can not be neglected. The model which takes the ablation effect into account is proved to be valid.

通过将考虑和不考虑烧蚀效应的数学模型数值计算所得的计算结果与试验结果相对比，说明了喷口烧蚀对上游压力升高的贡献不可忽略，并验证了考虑烧蚀效应电弧数学模型的正确性。

It can be concluded that, when the jet is injected at positive angles, the initial section of the jet increases and the region affected by the jet decreases in the vertical direction; moreover, the circumfluence toward the jet exit becomes more obvious, and the separation events in the lee of the jet weaken. When the jet is injected at negative injection angles, it disarranges the flow upstream and the curvature of jet trajectories varies smartly along the flow direction.

结果表明：射流正向倾斜入射时，射流起始段增加，在垂直方向对主流场的影响区域减小，射流喷口上游位置处的&孔吸流动&更为明显，射流出口下游背风侧的分离现象逐渐减弱；射流反向倾斜入射，对上游流场的扰动增加，射流在弯曲段内曲率变化大。

Next edition, I will be showing you how to create details such as the lights, radiator grills, vents,etc.

在下一个版本，我将显示你如何创建细节，如灯光，散热器的手艺，喷口，等等。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
